FREDERICK THOMAS SCHMIDT, OF BRADFORD, ENGLAND.

APPARATUS FOR CONSUMING SMOKE.

SPECIFICATION forming part of Letters Patent No. 447,367, dated March 3, 1891. Application filed November 5, 1889. Serial No. 329,267. (No model.) Patented in England July 11, 1889.110} 11,164.

To allwhom zit may concern:

Be it known that I, FREDERICK THOMAS SCHMIDT, a subject of the Queen of Great Britain and Ireland, residing at Bradford, in the county of York, England, have invented certain Improvements in Apparatus for Consuming Smoke, (for which I have obtained a patentin Great Britain, No. 11,164, dated July 11, 1889,) of which the following is a specification.

This invention relates to certain improvements whereby the smoke on leaving the lines of steam-boilers or other furnaces may be consumed or converted into heat by an apparatus constructed apart from the boiler or furnace and which may be connected to some portion of the flue and placed in a suitable position, and in such a manner that the smoke may be conducted thereto, where it is ignited and consumed or converted into heat, which may be utilized for the generation of steam in boilers or for other purposes.

In the accompanying drawings, Figure 1 represents a front View of the exterior of an apparatus suitable for carrying out my object, my smoke-consumer being illustrated in this view as applied to smoke-Hues (shown in section) of an ordinary steam-boiler furnace. Fig 1 is a corresponding plan with the fines shown in section. Fig. 2 is a vertical section through line 1 2 on Fig. 4; Fig. 3, a vertical sectiqn at right angles to Fig. 2 through line 3 4 on Fig. 4, and Fig. 4 is a plan through irregular line 5 6 on Fig. 2.

The invention is illustrated as it may be applied to a tubular boiler; but on reading the specification it will be apparent to engineers and others conversant with heatingfurnaces that the heat generated in the apparatus, as hereinafter described, may be utilized for other purposes besides that illustrated.

Referring to Figs. 1 and 1, the-steam-boiler or other furnace 1 may be of any well-known type, with a flue 2 leading .to the ordinary chimney or smoke-stack and provided with a damper at 3. A flue 4, which is provided with a suitable damper at 5, leads through a tube 0 to my improved consuming apparatus, whence the products of combustion pass off through a flue 6, as shown in Fig. 1.

Upon the frame-plate A of this apparatus,

Figs. 2, 3, and 4, rests one end of aseries of firegrate bars B, which may be level or inclined, as shown, the opposite ends of the bars being supported by the inner ring A of the framepla-te, upon which also rests the vertical. tube or channel 0, connected at its bottom end by the tube 0 to some portion of the smoke-flue leading from the steam-boiler or other furnace.

Upon the frame-plate A is built suitable brick-work D for inclosing my apparatus and forming a chamber in which the heat may be utilized, such as for generating steam, the boiler shown being one of the ordinary wellknown tubular type supported by a frame built in the brick-work. The smoke passing through the tube 0 may continue its course unobstructed and combine with the heat arising from the fire, by which it is ignited and consumed, but not so thoroughly as when a deflecting-plate E is suspended or otherwise supported above the tube 0, such plate being by preference concave on the under side and coated with ganister, fire-clay, or other refractory material F, as is also the exterior surface of the tube 0 at F. The fire-bars B in the space G between the central tube or channel O'and brick-work D are covered with fire, the same being fed with coke or other fuel and distributed through the doors H H, or when provided with a deflecting-plate E it may be thrown upon the upper or convex 'sidrk m of the deflector E, which distributes it on the grates below, the doors J J being for the purpose of allowing the fire to be agitated or cleaned whenever required,

On a fire being made in the space G the central tube or channelO is heated to redness, and on smoke being admitted thereto from a boiler or other flue by means of the connecting-tube C the smoke is heated in the said tube, and on its escape from the top of same combines with the heated gases from the fire in space G and is converted into inflammable gas and ignited, or when a deflecting-plate E is placed above the end of tube 0 the smoke impinging on the same is further heated and deflected through the annular space K between overhanging deflecting-plate E and top of tube or channel 0, thus causing the heated smoke more thoroughly to combine with the heated gases from the fire in space G, by

which it is ignited and consumed or converted into heat, which may be utilized for generating steam in a boiler placed in the same chamber L, as shown, or in a separate chamber connected by a flue, or may be utilized for other purposes requiring heat, such as annealing metals and the like placed in ordinary annealing-chambers connected to the chamber L above the deflecting-plate E.

hat I claim is 1. The combination of a steam-boiler or other furnace having a smoke-flue leading therefrom, with a smoke-consuming apparatus consisting of a tube, into which the said f urnace-flue discharges, and around this tube a fire-chamber which is in communication with the tube, as and for the purpose set forth.

2. The combination of a steam-boiler or other furnace having a smoke-flue leading therefrom, with a smoke-consuming apparatus consisting of a central tube, into which the said furnace-flue discharges, with a defleeting-plate over this tube and a communicating fire-chamber around it, all substantially as and for the purpose set forth.

3. The combination of a steam-boiler or other furnace having a smoke-flue leading therefrom, with a smoke-consuming apparatus consisting of a tube into which the said furnace-flue discharges, and around this tube
